Configuration Overview
To Make Configuration Changes Safely
1. Create a command file containing the SCF commands.
2. Save the current $SYSTEM.ZSYSCONF.CONFIG file using the SCF SAVE command described
in the SCF Reference Manual for G-Series RVUs.
3. Run SCF using the command file you created in Step 1.
4. If the new configuration creates a problem, you can return to the earlier configuration by
loading the system from the saved configuration file.
Using OBEYFORM to Create an SCF Command File
The OBEYFORM attribute of the INFO command can help you automate the task of configuring
objects by displaying configurable attributes in a form accepted by the ADD command.
You can use OBEYFORM on these objects:
• DISK, magnetic
• DISK, virtual
• MON
• POOL
• SCSI
• TAPE
Comparing OBEYFORM to LIKE
The LIKE attribute of the ADD command performs a function similar to the OBEYFORM attribute of
the INFO command:
• Use the LIKE attribute to quickly add one or more similar objects to the current configuration
file.
• Use the OBEYFORM attribute to see and change the attributes of new objects before adding
them to the configuration file.
• You can log configuration information for existing objects and use that information later to
add similar objects or to reconfigure objects that have been stopped or deleted.
By issuing successive INFO commands for each object, you can build a system-load command file
that reflects modifications you have made to your configuration.
You can copy this command file to another system to add the same configuration records to a
different configuration file.
